THE PRINCIPLES OF MYODYNAMICS. 69 



(2.) The altitude of the radial cone was about 

 nine and one-fourth inches in length. 



(3.) The slant height of the radial cone was 

 about nine and two-fourths inches in length. 



(4.) The axis of the radial cone prolonged 

 downward will nearly coincide with the long axis 

 of the ring-finger. 



54. The following dimensions of the quad- 

 rangle of the fore-arm were taken in the same 

 case :— 



(i.) One side of the quadrangle was about 

 one and three-fourths inches in length. 



(2.) The other side of the quadrangle was 

 about ten inches in length. 



(3.) The proximal end of the quadrangle of 

 the fore-arm is measured on the lower end of 

 the humerus. 



55. Flex the fore-arm so that its long axis 

 meets the long axis of the humerus at right 

 angles, and put the fore-arm in a position of 

 mid-rotation : — 



(i.) The plane of the bones of the fore-arm 

 will be nearly vertical. 



(2.) The long axis of the humerus will meet
